[Edit: "Dudes" should be read as a friendly term encompassing those of all genders or none :) .]
We are overdue a competition and with a major landmark looming it seems apposite to set the following questions:
a. On what date shall we become world #50?
b. Who will be displaced so we can claim this honour?
The prize goes contrary to TSBT tradition in that it might expand your intellect rather than reduce it

The Rules
Boincstats and I shall arbitrate the result.
My decision, however self interested, is final.
You can amend your guesses up until 15th November.
You have to be an active member of TSBT to enter.
So I shall venture the first guess:
24th November displacing Hungary.
